UNACs have maximum kick potential. I made a video out of mine. I dunno why it works but it does. LTA or LTB legs will probably help it out in close quarters since they turn way better than funeral. Also consider swapping starlight for a CE head since those have high stability computation which affects boosting/turning and should make it's boosting faster.

Wide-angle max lock is generally the preferred FCS for tanks in general just cause they turn poorly and it's the biggest FCS they can use.

How does the KE head help with the autocannons? KE heads generally have higher scanning performance at the cost of other things, which is useless on a UNAC. Balancing CE/KE defense is also important for survival.
